Comfort and well-being in every room

Most people in the industrial world spend some 90% of their time indoors. About one third of this time is spent at work. Against this background, it is clear that good indoor air quality, the right tempe-rature and draught-free air renewal are vital prerequisites for motivation and a sense of well-being. The Desigo RXC room automation system provides individual demand-based comfort for the users of public buildings, offices, schools, hotels, etc.

The room controllers and room units in the Desigo RXC range control and monitor comfort conditions in rooms and self-contained zones. These functions are finely tuned to the specific requirements of the area concerned (room or zone).

This makes it possible to satisfy individual comfort requirements and create a sense of well-being while at the same time saving energy.

Easy control of HVAC, lighting and blinds

The modular design of the Desigo RXC range means that if required, the operation of lighting and blinds can be combined with HVAC control. Using just one operator unit, room users can adjust all the room functions to suit their requirements.

Stand-alone operation at field level, or integration into the building automation and control system

The devices in the Desigo RXC range communicate with each other and with other LONMARK-compatible devices using a standard protocol (LONMARK® over LON bus). If required, devices at the field level can be integrated seamlessly into the Desigo building automation and control system. This is where all the higher-level control and coordination tasks, such as time scheduling or energy optimization activities are performed.

The Desigo RXC software

All the room controllers, and the flexible room unit, are loaded with application software (referred to here simply as the "application") which contains the control program for the associated room or area. The devices are pre-programmed with the required appli-cation before they leave the factory.

Siemens Building Automation maintains a comprehensive library of applications covering a wide range of HVAC and electrical applications (see the overview on page 10).

The RXT10 commissioning and service tool is used for the engineering and commissioning of a network incorporating the Desigo RXC range. This tool also supports the creation of communications bindings between LONMARK-compatible devices (Desigo RXC or third-party devices).

The room controllers

RXC10, the room controller in a room-style housing:

This controller is a cost-effective combination of a room unit and an HVAC controller. It is particularly suitable for radiator-and-chilled-ceiling applications, and for simple VAV systems.

RXC20, RXC21, RXC22 and RXC39 compact room controllers

The input / output configuration and mounting options of these controllers make them ideal for fan coil applications. They can be installed in the fan coil unit, in control panels or on ducting.

Applications for radiators and chilled ceilings are also available.

RXC32 compact room controller

The RXC32 controller is particularly suitable for standard single-duct VAV systems. It comes with a built-in volume sensor.

RXC30 and RXC31 modular room controllers

The RXC30 basic module is fully optimized for radiator and chilled-ceiling control as well as the control of two rows of lights.

The RXC31 basic module provides flexible control solutions for VAV supply and extract air systems. A configurable interface (DC 0 ... 10 V) permits the connection of compact volume controllers.

The RXC31 basic module is designed for special applications.

RXC40 and RXC41 extension modules for lighting and blinds

The modular room controllers RXC30 / 31 / 38 can be combined with either one or two extension modules, type RXC40 and / or RXC41. These are simply plugged into the basic module. As a result, only the basic module needs to be loaded with an application and connected to the LON bus.

The RXC40 extension module allows two additional rows of lights to be switched and dimmed; the RXC41 module permits the switching of two drive motors for blinds.

Free scope for mounting

Apart from the RXC10, the room controllers can be mounted wherever preferred (e.g. in ceiling voids, under floors, in VAV boxes, ducting etc.).

Inputs and outputs

The range of functions of the inputs and outputs is determined by the particular application and its parameters. For example, the AC 24 V outputs can be configured for thermic valve actuators or for 3-position actuators (depending on the application).

The room units: the key to individual comfort

The room units in the Desigo RXC range cover a wide variety of needs represented by the various room occupants. When designing these stylish room units, the designers also paid special attention to ergonomic factors.

The HVAC system, lighting and blinds can be operated in various ways:

• In the conventional manner, with standard room units for HVAC, and electric switches to control lighting and blinds

• With the integrated room unit, which combines the operation of HVAC, lighting and blinds in a single device.

• With wireless room units, which offer scope for location anywhere in the room, and permit averaging.

Conventional room units

The standard room units, types QAX30.1 ... QAX39.1, are available for HVAC appli-cations. They are connected to the room controller via a special (PPS2) interface. In addition to the built-in temperature sensor, all room units incorporate a socket for the RXT10 commissioning and service tool.

For applications involving the control of lighting and blinds, conventional switches can be used. This option is primarily of interest in systems retrofitted with Desigo RXC.

Integrated room units

The QAX50 and QAX51 flexible room units combine the operation of HVAC, lighting and blinds in a single device. The functions of each room unit are defined with appli-cation software in accordance with the room configuration. The room units are then fitted accordingly with the appropriately labeled pushbuttons. These integrated room units communicate with the room controllers via the LON bus.

Flush mounting room units with elegant design

The QAX84.1/PPS2room unit can be used in connection with standard switches and for in-wall mounting. It is delivered with a Siemens Delta-I bezel, but can also be ordered in separate components to fit in bezels from various manufacturers: Operator unit (QAZ84.1) and PPS2 flush mounting bus coupling unit (RXZ80.1 / PPS2).

Wireless room operation

The wireless room units, types QAX90.1 and QAX91.1 are used in conjunction with the RXZ90.1 receiver (PPS2). They are ideal for:

• Use in renovation projects (no wiring required) • Rooms with flexible partitioning and furnishing • Simple derivation of average temperature values (max. 5 sensors)

EnOcean room units

The batteryless and wireless room units, types QAX95.1 and QAX96.1 are used in conjunction with a gatewaRXZ95.1 (LONWORKS).

Applications

The scope of the Desigo RXC range is defined by the pre-programmed application software. The next pages provide an overview of the options available and the devices required.

The applications can be downloaded with the RXT10 commissioning and service tool, which contains the complete applications library.

Due to intelligently defined default values in the applications, engineering involves simply determining a small number of parameters, e.g.:

• 2-position or 3-position control of valves and actuators • Temperature setpoints • Manual or automatic fan control For the complete list of applications, refer to the currently valid compatibility list (Valid Version Set) in the applications library, document CA110300.

Basic applications

With the basic application software every room controller can also be used as an I/O module. The RXT10 commissioning and service tool can be used to view the signals at the hardware inputs or to process them further at the automation level or on the management station. Similarly, the outputs of the room controllers can be controlled directly via inputs.

If a room controller is ordered without an application being specified, it will be pro-grammed in the factory with the appropriate basic application before delivery. Appl. Description

Engineering and commissioning

In the engineering phase, the number of devices, their application and the LONMARK bindings between devices, and between these devices and any third-party equipment are determined according to the distribution of rooms and zones in the building.

The network structure defined at the engineering stage (applications, parameters, LONMARK bindings etc.) is mapped to the devices in the commissioning phase.

RXT10 commissioning and service tool

The RXT10 commissioning and service tool provides efficient support both for engineering in the office and for commissioning on site. (In Desigo V5 we also admit the use of standard LNS tools, e.g. NL220, LonMaker).

The RXT10 software is designed for use on a PC running Windows XP or Windows Vista.

The commissioning and service tool is used for the following:

• Selecting the application for each room • Determining the required room controllers and setting their parameters • Integrating LONMARK-compatible third-party devices (e.g. LNS plug-ins) • Creating the LONMARK bindings • Dividing the network into segments and adding routers • Addressing the controllers • Loading the network structure (including applications) into the devices • Commissioning support • Project documentation • Graphics-based network view • etc.

Selecting the application and controllers

From the comprehensive application library, first the appropriate application is selected and then the appropriate devices (in the example below, this means application INT06 and the RXC30 basic module with extension modules RXC40 and RXC41).

Selecting the application

15

Parameter setting

Each application has a number of parameters, such as temperature setpoints, type of output sequence (2-position or 3-position), type of fan control etc. These parameters are now adjusted according to requirements. In most cases, however, the factory default settings can be retained.

Setting the temperature setpoints

Communication bindings

The bus communications in the Desigo RXC range are based on LONWORKS techno-logy. This allows devices to communicate with each other and with LONMARK-compa-tible devices from other manufacturers. So, for example, an outside temperature sensor can be connected to a number of room controllers via the LON bus.

Changes in building use can also be accommodated without the need for rewiring, simply by changing the bindings, e.g. master / slave.

The graphical user interface of the RXT10 tool can be used to create these LONMARK bindings with a convenient "drag and drop" operation.

Example: Creating bindings

16

Addressing

The physical identification number (neuron ID) of each device (Desigo RXC or a LONMARK-compatible third-party device) must be modified to match the logical address (e.g. location) in the network structure. The RXT10 tool offers various options for efficient addressing.

Loading the network structure

The network structure (applications, parameters, LONMARK bindings) must now be mapped in the individual devices: On site, this can be carried out from any point on the LON bus. It is also possible, however, to address the devices individually and download them with the network structure prior to installing them on site.

Connection of the RXT10 commissioning and service tool

For commissioning on site, a laptop running the RXT10 tool software is connected to the LON bus. All the Desigo RXC devices on the LON bus can be addressed from this point. If the room controllers are installed in a location where they cannot be seen, a room unit can also be used for access to the LON bus: all the room units also incorporate a tool socket.

Adjusting the parameters

If necessary, parameters such as temperature setpoints can be adjusted during com-missioning or later when servicing the system.

Commissioning support

The RXT10 tool includes convenient functions to support commissioning and service, for example:

• Interrogating or restoring network data • Monitoring and testing the inputs of one or more controllers • Direct control of the outputs of one or more controllers for test purposes or to

balance hydraulic circuits • Trend features for long-term data logging • Report functions for printing project data

Stand-alone operation at field level

The Desigo RXC room automation system can be operated as a stand-alone system. All the required functions are made possible by means of LON communications be-tween the devices.

Integration into the automation level

Through integration into the Desigo PX automation level, a number of further functions become available (refer to the PX system description, document CM110756).

The room level is integrated into the automation level by means of the system controller PXC....D + PXX-Lxx. This controller converts the LONMARK objects into BACnet objects, and provides comprehensive grouping functions. Up to 60 room controllers can be connected to each PXX-L11 system controller, and up to 120 to each PXX-L12 system controller.

Features of the system controllers PXC....D + PXX-Lxx:

• Concentration of data of the room controllers, and easy manipulation of this data • Simple definition of groups • Implementation of system functions, e.g. time schedules, trends, alarms etc. • Coordination with the primary plant • Efficient engineering and rational commissioning

Features of the PXM20 / PXM20-E operator unit

• Operation and monitoring of the entire automation level including inputs, outputs and the room-controller operating states.

• Display and modification of time schedules • Graphics-based display of trend data

18

Integration into the management level

Because it is integrated into the automation level, the room level can also be displayed and operated at the management level.

DESIGO INSIGHT is the Windows XP / Vista-based management station within the Siemens building automation and control system. With its modular structure it covers every level of complexity - from small buildings to large building complexes and geographically separate buildings For more information refer to the Desigo system description, document CM110660.

Depending on the degree of complexity required, the DESIGO INSIGHT management station may incorporate, for example, the following program modules for the user:

• Plant Viewer: graphics-based operation of the plant • Time Scheduler: time schedules for a wide range of switching operations • Object Viewer: display and modification of data point values • Alarm Router: routing of alarm messages • etc. The DESIGO INSIGHT management station allows the following additional functions for control and operation of the room controllers:

• Monitoring and operation of rooms, plus trend logging • Building use and room occupancy time schedules • Integration of the controller data into plant graphics • Central control of setpoints, operating modes, lighting, blinds etc.

For every standard application a suitable super genie is available in DESIGO INSIGHT

19

Time schedules for building use and room occupancy

One option which is frequently employed at the automation level or in the DESIGO INSIGHT management station is the use of central Building use and Room occupancy time schedules. These make it possible to optimize the supply of energy to match varying periods of room occupancy.

The Building occupancy time schedule determines the overall period of time during which the building is in use. Outside this period, the plant (e.g. HVAC primary plant) remains available, but at reduced output.

The Room occupancy time schedule determines the occupancy times in individual rooms or groups of rooms. This enables individual tenants of the building, for example, to define their own occupancy hours.

Central and local control of operating modes

The diagram below shows an example of how the central time schedules (Building use and Room occupancy) interact with the local / Auto control button on the room unit

(operating as an occupancy function in this case).

Local control with an occupancy sensor is also possible.
